I have the free version of limewire on my computer and it runs fine. I have Windows XP. I was thinking about upgrading to Pro. I was looking at the refund policy page on the internet. I saw the part that said you should run a test on your computer before you purchase pro. I ran the test and a black box came up for only a second saying "Connecting To 64.61.25.171...". It never said "Gnutella OK". So I'm not exactly sure what the test results were. Should I upgrade to pro? I'm not sure what to do. I don't want to pay for something that isn't going to work. Please help me.
